SSH under Windows

Openssh with Powershell

Windows offers a fully fledged openssh client (https://learn.microsoft.com/en-us/windows-server/administration/openssh/openssh-overview). Thus the same methods as with Linux/Mac OS X are working.

Open the Terminal app and setup our SSH CA first:

"@cert-authority *.asc.ac.at ecdsa-sha2-nistp256 AAAAE2VjZHNhLXNoYTItbmlzdHAyNTYAAAAIbmlzdHAyNTYAAABBBADeLjSj4J0MFrdxdn9M/mcZi1fqKnQB6ZHjysUlontzFXI9PVoxPjYqMDDO0hM6IM6NCnkiiFqveEvSoXDnGWI=" | Add-Content .ssh\known_hosts

Now you can login via the device auth flow

With Step SSH Certificate

step needs a running ssh-agent, execute the following commands to enable the ssh-agent on your system.

First open a Terminal (Admin):

# By default, the ssh-agent service is disabled. Configure it to start automatically.
# Run the following command as an administrator.
Get-Service ssh-agent | Set-Service -StartupType Automatic

# Start the service.
Start-Service ssh-agent

Then install step:

winget install Smallstep.step

Now you can bootstrap step ssh on your machine.

step ca bootstrap [--context asc] --ca-url https://auth.asc.ac.at:9000 --fingerprint 44b048473242281db1da57124c2b843741d6c92a8fb5d0482dec032e957f2919 

After login you can use ssh as usual without being asked to login again.

step ssh login [--context asc]

ssh [-A] [-X] <username>@musica.vie.asc.ac.at

VSCode

A convenient way to work with our system is VSCode with the Remote Development extension. When you have setup your environment with step ssh as described above, the extensions work out of the box.
